IMPROVEMENT IN REAPlNG-MACHINES.

Specification forming part of Letters Patent No. 5,227, dated August 7, 1847. f

T0 at! whom it may concern:

Beit known that I, OBED HUSSEY, of the city of Baltimore, in the couutyof Baltimore and- State of Maryland, have invented anew and useful Improvement on the Reaping-Machine invented by me and patentedin 1833; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which Y Figure 1 is a birds-eye view of the cutting apparatus, in which A A A A A A'.represent the vibrating cutting-blades B'B B B B B, the permanent guard-irons. H represents a part of the wood-work. The guards are formed of a lower piece and an upper piece admitting the blades to pass between in cutting, so that the straw, grass, hemp, corn, &o., which comes in between. the guards to be cut is firmly supported both above and below the vibrating blades.

In my original invention the upper part '0 the guards were fastened to the lower part both before and behindthe blades, as represented at O 0 O C. The grass, straw, 850., which is not perfectly cut is forced in by the motion of the blades and works back between the blades and the upper pieceof the guards,

materially obstructing thefree movement of the blades in wet weather, frequently causing W hat farmers call choking.

The improvement for which a'patent isnow asked is represented at D D1) D where the.

upper piece of the guard is fastenedto the lower piece only at the point, leaving the .back end unconnected. Consequently the space be tween the upper and lower-pieces of the guards through which the blades vibrate is open be hind, so that the grass, 860., which is forced in' by the action of the blades now passes freely out through the opening,'which opening, when used in combination with vibrating blades, constitutes a claim in thisimprovement and is represented at D D'DD, Fig. Land at A, 'ig. 3.

in my original invention.

My improvement extends, also,." to the pre: vention of the accumulation of grass, 8to., un-' der the blades, which I will describe as follows:

. In my original invention the blades are ground with a bevel on both sides of'theedge. The purpose'o'f this'is,that by means of the shoulder of the bevel the sharp -edge i'sprcven ted 'fromcomin g inim mediate contact with the iron in passing the guard. This bevel is not so necessary near the fork of the blades as near their points. Hence in this improvement about one inch of edge at the'fork-is flush on. the under side, leaving the bevel all on the upper side. The design of this is thatthe grass, &c., whichis forced in between theblades and the lower part of the guard shall a be out up and worked 'out by the flush edge, acting close to the iron at the fork. This latter improvement is also claimed as. new in its application to the particular purpose for which it is designed.

Fig. 2 is asectional view of one of the guards wood=work, as seen at H, Fig. 1.

Fig. 3 represents one of the guards contain,- in g the improvement before described. A is the opening. B part of the wood-work.

Fig. 4 represents a view of one of the blades with its flush edge E E on each side of and at the fork of the blades A.

I accordingly claimv 1. The opening above the blades at A, Fig. 3,-an'd at D, Fig. 1, in combination withvibrating blades. "2.1he particular application of the flush edgeat'the fork of the blades, for the purpose described. g

The end and design 'of the improvements above'cl-aimed' is to prevent the blades choking;
